Dynamic Timing
Hey all,
I'm going to be looking at doing the injector pump belt on my v70 2.5d in the coming month, I've a few questions that may be common sense, but I'll ask anyway! I've read every "how-to" guide going I think, but I've never had anything to do with timing belts on anything. There are two idlers/tensioners, upper and lower. Do these need replacing every time the belt is done? The belt it self - A technique I've seen done is to slice the old belt down its length, remove half, then slot the new belt on the exposed pulleys, then remove the remenants of the old belt. Do we think this would work on the injector pump belt? Is there anything else I should do whilst I'm in there? The Cam belt and water pump was done 3k ago and I have access to VIDA/dice so I can run the dynamic time set-up and adjust when I'm done - I believe the instructions are to adjust this whilst running the engine, has anyone actually done this? And lastly, is there anyone local to York, Malton etc. that would be willing to give me a hand with this? Happy to chuck beer tokens etc about - I have a nice dry, warm workshop to do this work in! Cheers Ben |

Hello Ben.. I can't say as I've performed the belt slice thing, but you need to know that there's a locking screw on the side of the pump. The photo is stock off the internet, but you can see the locking screw on the main boss of the pump.
You undo the locking screw with your old belt and timing set up in situ, remove the spacer bracket on the locking screw, and then put the screw back in and nip it up. This will lock the pump in situ allowing you to remove the old belt and fit your new one. Don't forget to remove the locking screw and refit the spacer bracket once the new belt is on. Its critical of coarse that the engine is not turned in any way. Re the idlers and tensioners, if you don't know how long they've been in there I'd change them. If you require a PDF on the set up of this pump PM me with an email address and I'll send you one. Dave..

Personally now I just time everything up as over the years it appears most of the camshafts have moved and they run much better if everything is where it should be!
So messing about cutting belts etc would most likely be a waste of time!
